“I spy a giant Rubik’s cube,” writes Chad Rupley. Described as “cool” and “lovely” by Gen Stewart and Kim Perlman, respectively, the outsize cube was designed by two teams of engineering students. “To spin [it], you would need to get inside the G.G. Brown Building,” notes Ken Koral, who entered the contest with his son–it’s also known as “the mechanical engineering building on North Campus,” writes Marianne Flinn.
Eric Sobocinski points out that the photo shows the cube “through the glass wall from the walkway to the west.” This made the contest “a bit of a challenge,” writes Bob Baird, referring to the fact that the cube isn’t actually visible from the street. “Very clever,” he writes, “both the cube and the contest.”
“It took 3 years to construct … the ‘world’s largest, stationary, human manipulable Rubik’s Cube,'” writes Tim Reade. “I hope to visit it soon as my nephew is starting as a first-year Engineering student.” Jennifer and Lucia Manning went to “spin this giant cube … [but] missed the attendant’s time frame.” The cube is typically available for solving weekdays from noon to 1.
We received forty-five entries, forty-two of which correctly identified the Rubik’s Cube at G.G. Brown. Our winner, drawn randomly from among the correct entries, is Tim Reade of Huntington Woods. He will enjoy his $25 gift certificate at Zingerman’s.
